ABOUT BOLTS

We as Bolt fasteners supplier leverages the parametric abilities that most CAD applications provide.Bolts can secure material by applying pressure from the head of the bolt.In other words, bolts are manufactured by forging cum threading process. Apart from the strength benefits (a fastener properly threaded or a bolted joint is much stronger than unthreaded bolts or screws) bolts are also reversible, which means they can be taken apart after they are assembled. They are quite cost- efficient & available in a varied range of sizes. Since threaded fasteners like bolts can be used many times in a single application. They can add extra advantage to a product. Additionally, they often need re-tightening when located in unstable places. They are susceptible to variations and many safety wires or other added features to further hold in place and enable proper performance.
TYPES OF BOLTS:
Carriage bolts – Bolts with a proper finish cum round head that have a small square section underneath are called carriage bolts.

Hex Bolts – These are used in machinery and construction. Fully threaded hex bolts are also called tap bolts.

Lag bolts – Bolts with a wood thread ad pointed tip.

Wood bolts – These have long threads and a smooth shank for pulling two pieces of material together, they can be used in wood and other soft materials.

Eye bolts – A bolt with a circular ring on the head end used for attaching a rope or a chain.

J- Bolts – J-shaped bolts are used as tie downs or fastened as an open eye bolt.

Elevator bolts – Elevated bolts are moreover used in conveyor systems. They have a large flat head.

U- Bolts – Bolts in U shape are used for attaching to pipe or either round surfaces. Also available with a square bend.

Shoulder bolts – named as stripper bolts are used to create a pivot point.

MATERIAL USED

Bolts as Fasteners come in a varied set of materials. Selecting a material should be based on following considerable environment (corrosive or temperature extremes), weight, magnetic properties, stresses, re-usability, & expected life.

Fasteners are available in following as given: Stainless Steel and Alloy Steel Materials such as SS304, SS316, Monel, Inconel, Incoloy, Hastelloy

Duplex Steel, Super Duplex Steel, Titanium, Tantalum and other alloys as per requirement and application.

We are 100% sure for our in house tested zero defect tube and 3 layer inspection control of mechanical test, chemical test, dimension assessment, pressure test and gauge test. We are normally packed with loads of orders this is why we schedule 90 days prior in advance to avoid last minute rush.

In Steel tubing we usually recommend to do surface cleaning to remove all impurities within the stock. When it get dried up, then later on it is used to wrap within with thin layered plastic sheets. All the required ends are protected by plastic cap to avoid any unexpected damages with respect to transition from one place to another during transit. At last but not the least the tubing is bundled with bubble wrap followed by colored plastic goonies or set of bundles.The outer rope is tied to protect the tubing which are packed in wooden box as final finishing to the qualitative packaging.We follow all this process so that the customer will able to track or identify ordered product safely at receiving end. We are giving emphasis on packing as much as production and like to make seamless buying experience for customer.We provide tube with required documents prior to dispatch of tube from home mill unit, such as packing list, commercial invoice, Test Reports, HS Code, Country of Origin attested by chamber of commerce, Fumigation Certificate, Warranty Letter, and Base Material Certificates.On client request we also provide a free sample kit against purchase order copy. The client just need to click on “Request your free sample kit now!” button on our digital online web link.

Raw material inspection & storage.

Raw material for the bolt is to be decided by the designer based on its application.

Material to be used is supposed to be inspected & then proper warehouse location is to be identified in order to avoid rust formation cum proper coverage needs to be provided.

Unthreaded bolt manufacturing.

Moreover casting & forging are used in this stage.
Other methods may also be lined up e.g. sintering & prototyping.

Manufacturing is followed by following methodology:
CNC MACHINING:

Manufacturing of part is executed thru forging/casting method. It is then machined to the specific dimensions generally by CNC. The operations followed here are namely pointing, facing and grooving.
HEAT TREATMENT:

Heat treatment will proceed after machining is done to make the fasteners tensile strong. Hardening & tempering operations are then followed. Hardening is done on bolt and it get heated to a temperature of 850-900 degree & then quenched in the cooling media. Later on the bolt is again re-heated to bring back the complete hardened bolt less soft, so that the bolt remains strong enough. Re-heating is done to bring down the brittleness of the bolt which happened during hardening.
SURFACE FINISHING:

Normally, grinding process is carried out to make the surface smoother according to the surface finish requirement.
THREAD ROLLING:

The Next steps followed by thread rolling with two dyes. One is stationary & another is a moving dye which actually exerts force on the bolts & forms threads. Threads on bolts may be fine, medium cum coarse depending upon the application of the bolt.
COATING:

Then, bolt fasteners are coated in order to avoid rust & corrosion. A fine example of bolt coating is geomet coating in bolts which is tested to salt spray test, depending upon the number of hours as mentioned. Machinery is used to determine coating thickness along with other different measuring instruments e.g. coating thickness meter.
